RADIATOR.

l Application filed February 13, 1928.

This invention relates to motor vehicles and particularly to the means for supporting the radiator on the frame.

The cores of vehicle radiators used in the past have always been rather rigidly secured to and supported by the radiator shell. lt has been found from very extensive tests that in a great number of cases the radiator -core has been ruptured by the weaving and twisting of the vehicle frame when the vehicle is operated over rough and uneven roads. One side rail of the frame moves relative to the other, causing the radiator shell to become distorted and to transmit the twisting stresses therein 1.5 to the radiator core. Because of the fact that the core is built up of a plurality of thin copper tubes, the twisting stresses quite frequently rupture the same. Itis therefore, the principal object of the present invention to pro- 21.) 'vide a new and novel means for supporting a vehicle radiator which means prevents twisting stresses from being transmitted to the radiator core.

Another object is torprovide a vehicle radiator with a three-point suspension for the core thereof whereby twisting stresses in the radiator shell are absorbed to prevent the same from being transmitted to the core. y

A further object is to provide a vehicle radiator shell with a pair of ball members seated in spherical depressions at the sides of the radiator core to support the same and to absorb the twisting stresses which would ordinarily be transmitted to the core from the vehicle frame and radiator shell. j These being among the objects of the present invention, the same .consists of certain features of construction and combinationsof parts to be hereafter described with reference to the accompanying drawing and then claimed, having the above and other objects 1n view.

In the accompanying drawing which il-` Serial i No. 254,016.

tion of the Lipper portion of the radiator taken on the line 4-4 of Figure 2.

Figure 5 `is a transverse section taken through` a modified form ,of radiator support.

Referring to the accompanying drawing in which like numerals refer to like parts throughout the several views, the vehicle radiator shell 10 is supported on the vehicle frame side rails 11 by means of a pair of angle brackets 12 secured to opposite sides of the shell 10. rlhe horizontal legs of the angle brackets 12 are preferably secured to the upper flanges of the frame side rails 11 by suit-V able bolts 13. f A l Angle members 14 as shown in Figure 3 are 1 secured to the inner side faces of the shell 10 70 by the rivets 15 which also secure the supporting brackets 12 to the outer side faces thereof. The short legs of the angle members 14 face inwardly toward each other and each is provided with a secondary angle member 16l secured by rivets 17 or any other suitable means to the inner faces of the llegs thereof. The horizontal leg of the angle member 16 reinforces and gives added thickness to the horizontal leg of the angle member 14. The hori- 30 zontal legs of the angle members 14 and 16' are provided with coaxial openings which are tapped to receive a screw 18 which is preferably formed with a spherically-shaped head 19 for a purpose which will be described later 85 in the specification. y

The metal surrounding the :filler pipe open-V ing at the upper portion of the radiator shell 10 is depressed at 24 to form a seat for a coil spring 25. When the radiator is assembled a filler pipe 26 projecting upwardly from the radiator core 20 extends through the coil spring 25 and projects through the liller pipe j opening'of the shell 10, the spring 25 being seated in the depression 23 and seated against 95 a portion of the upper water header of the core 20.

The radiator Vcore 2O has a supporting bracket 21 suitably secured to each end of the lower water header 22, which bracket is formed with a spherical depression 23 in av horizontal face thereof corresponding in shape to the shape of the head 19 of the screw 18. The screws 18 are threaded through the coaxial openings in the horizontal legs of the angle members 14 and 16 until the sphericalshaped ends 19 thereof seat in the depressions 23 of the supporting members 21 of the radiported only at two points on ball and socket supports, distortion of the shell 10 causes the spherical ends 19 of the screws 18 to universally pivot in the depressions 28 which prevents `the twisting stresses in the frame 1l and shell 10 from being transmittedto the radiator core 20. The spring Q5 surrounding the filler pipe 26 forces the core downwardly so that the same will not be inadvertently moved from its supports and also permits movement of the radiator shell 10 relative to the core 20. If the core 2O were rigidly connected to the shell 10 as is the case in the conventional radiator supports previously used, the twist-v core 2O and rupture the water tubes thereof.

.In Figure 5 a modification of the radiator core support illustrated in Figure 8 is shown. In this modification the radiator shell 49 is t supported at each side on the frame side members 41 by an angle bracket 42 and is rigidly secured thereto by a bolt 43. "An angle member 44, similar to the angle members 14 shown in Figure 3, has an inner' anglemeinber 45 n secured to its inner faces and is attached to the inner side face of the radiator shell 40.

' 47 of the screws 46 to .pivot in the bracket openings 48 and thereby compensate for the twisting stresses in the shell 40 to prevent the same from being transmitted to the radiator core 50.

It is apparent that the present invention has many advantages which are not present in radiator supports used prior to this time. Tlhe radiator shell can twist and move with the vehicle frame without transmitting the twisting stresses to the radiator core which might rupture the tubes thereof if it were rigidly secured to the shell. This construction is very simple and is easy toassemble because of the fact that there are no small screws and nuts used to secure the radiator core to the. shell.

Y Formal changes may be made in the invention described without departing from the spirit and substance of the broad inven` tion, the scope of which is commensurate with the appended claims.

What I claim is:

1. The combination with the chassis frame of a motor vehicle, of a radiator shell mounted on said frame, a radiator core within said shell, brackets secured to opposite sides of said shell, and ball members supported by said brackets having pivotal contact with opposite sides of said core to support the same and prevent twisting of said shell.

2. The combination with the chassis frame i of a motor vehicle, of a radiatorfshell rigidly mounted on said frame, a radiator core having spherical depressions at its lower corners, brackets secured to opposite sides of said shell, and bolts threaded through said brackets having spherical ends engaging said depressions to pivotally support said core within said shell and eliminate the transfer of twisting stresses from said shell to saidr core.

3. The combination with the chassis frame of motor vehicle, of a radiator shell rigidly mounted on said frame, a radiator core within said shell, ball members carried by opposite sides of said shell pivotally supporting sai-d. core, and a spring interposed between the top of said shell and said core for holding said core in engagement with said ballmembers.

4. The combination with the chassis frame of a motor vehicle, of a radiator shell mounted on said frame, brackets secured to opposite sides of said shell, a radiator core within said shell, brackets having spherical depressions therein secured to opposite sides of said core, and ball members carried by said first brackets seating in the depressions in said .second brackets to support the opposite sides of said core for pivotal movement relative to said shaft.
